EN ISO 21225-2:2018

Plastics piping systems for the trenchless replacement of underground pipeline networks - Part 2: Replacement off the line by horizontal directional drilling and impact moling (ISO 21225-2:2018)

ISO 21225-2:2018 specifies requirements and test methods for pipes and fittings which are part of plastics piping systems for the trenchless replacement of various underground pipeline networks, underground non-pressure and pressure drainage and sewerage networks and underground water and gas supply networks, by means of horizontal directional drilling and impact moling.
ISO 21225-2:2018 is applicable to polyethylene (PE) pipes and fittings, as manufactured, as well as to the installed replacement system.
ISO 21225-2:2018 is intended to be used in conjunction with standards applicable for the construction of PE pipeline systems where available.
Regarding manufactured pipes it is applicable to three different PE pipe types:
-      PE solid wall single layered pipes (nominal outside diameter, dn), including any identification stripes;
-      PE pipes with co-extruded layers on either or both the outside and inside of the pipe (total outside diameter, dn), as specified in Annex A, where all layers have the same MRS rating;
-      PE pipes (outside diameter, dn) having a peelable, contiguous, thermoplastics additional layer on the outside of the pipe ("coated pipe"), see Annex A.
In addition, ISO 21225-2:2018 is applicable to:
-      jointing of pipe lengths by means of butt fusion joint to form continuous strings prior to installation;
-      fabricated and injection-moulded fittings made of PE.
Pipes made from other plastics, e.g. polypropylene (PP) are outside the scope of this document.
ISO 21225-2:2018 is not applicable to push-fit jointed discrete pipes assembled as part of the trenchless installation process.

Kunststoff-Rohrleitungssysteme zur grabenlosen Erneuerung von erdverlegten Rohrleitungsnetzen - Teil 2: Erneuerung in anderer Linienführung durch Horizontal-Spülbohrverfahren (HDD) und Bodenverdrängungsverfahren (ISO 21225-2:2018)

Dieses Dokument legt Anforderungen und Prüfverfahren für Rohre und Formstücke fest, die Teil von Kunststoff Rohrleitungssystemen sind und die mithilfe von Horizontal-Spülbohrverfahren (HDD) und Bodenverdrängungsverfahren zur grabenlosen Erneuerung von verschiedenen erdverlegten Rohrleitungs¬netzen, erdverlegten drucklosen Entwässerungsnetzen und Abwasserdruckleitungen und erdverlegten Wasser  und Gasversorgungsnetzen verwendet werden.
Es gilt für Polyethylen-(PE )Rohre und Formstücke „wie hergestellt“ sowie für das eingebaute Erneuerungssystem.
Dieses Dokument ist für die Verwendung in Verbindung mit Normen vorgesehen, die für die Konstruktion von PE Rohrleitungssystemen gelten, wenn verfügbar.
Bezüglich hergestellter Rohre gilt es für drei verschiedene PE Rohrarten:
—   einschichtige PE Vollwandrohre (Nenn Außendurchmesser dn), einschließlich jeglicher Kenn-zeichnungsstreifen;
—   PE Rohre mit koextrudierten Schichten auf entweder der Innen  oder Außenseite des Rohrs oder beiden (Gesamt Außendurchmesser dn), wie in Anhang A festgelegt, wobei alle Schichten über die gleiche erforderliche Mindestfestigkeit verfügen;
—   PE Rohre (Außendurchmesser dn) mit einer abziehbaren, zusammenhängenden, thermoplastischen Zusatzschicht auf der Rohr Außenseite („beschichtetes Rohr“), siehe Anhang A.
Zusätzlich gilt es für:
—   das Verbinden von Rohrlängen durch eine Stumpfschweißverbindung, um vor dem Einbau durchgehende Stränge zu erzeugen;
—   vorgefertigte und Spritzguss Formstücke aus PE.
Aus anderen Kunststoffen hergestellte Rohre, z. B. Polypropylen (PP), sind nicht im Anwendungsbereich dieses Dokuments enthalten.
Dieses Dokument gilt nicht für mit Steckmuffen verbundene Einzelrohre, die als Teil des grabenlosen Einbauprozesses zusammengebaut wurden.

Systèmes de canalisations en plastique pour le remplacement sans tranchée des réseaux de canalisations enterrés - Partie 2: Remplacement hors ligne par forage horizontal dirigé et fonçage par fusée (ISO 21225-2:2018)

L'ISO 21225-2:2018 spécifie les exigences et les méthodes d'essai appliqués aux tuyaux et raccords intégrés aux systèmes de canalisations en plastique pour le remplacement sans tranchée de différents réseaux de canalisations enterrés, des réseaux de branchements et de collecteurs d'assainissement enterrés sans pression et sous pression, ainsi que des réseaux d'alimentation en eau et de distribution de gaz enterrés, par forage horizontal dirigé et fonçage par fusée.
L'ISO 21225-2:2018 s'applique aux tuyaux et raccords en polyéthylène (PE), tels que fabriqués, ainsi qu'au système de remplacement, une fois installé.
L'ISO 21225-2:2018 est destiné à être utilisé conjointement avec les normes applicables à la construction de systèmes de canalisations en PE, lorsqu'elles sont disponibles.
Pour ce qui est des tuyaux fabriqués, il s'applique à trois types différents de tuyaux en PE:
-      tuyaux en PE monocouches à paroi compacte (diamètre extérieur nominal, dn), y compris les bandes d'identification éventuelles;
-      tuyaux en PE avec des couches co-extrudées à l'extérieur et/ou à l'intérieur du tuyau (diamètre extérieur total, dn), tels que spécifiés dans l'Annexe A, toutes les couches ayant la même classification MRS;
-      tuyaux en PE (diamètre extérieur, dn) comportant une couche thermoplastique supplémentaire pelable et contiguë à l'extérieur du tuyau («tuyau revêtu»), voir l'Annexe A.
En outre, l'ISO 21225-2:2018 s'applique également:
-      l'assemblage des longueurs de tuyau par soudage bout à bout pour former des trains de tuyaux continus avant l'installation;
-      les raccords en PE façonnés et moulés par injection.
Les tuyaux fabriqués dans d'autres plastiques, par exemple en polypropylène (PP), en dehors du domaine d'application du présent document.
L'ISO 21225-2:2018 n'est pas applicable aux tuyaux courts à emboîtement instantané assemblés dans le cadre du processus d'installation sans tranchée.

Cevni sistemi iz polimernih materialov za zamenjavo cevovodnih omrežij, ki so položeni v zemljo, brez izkopa - 2. del: Zamenjava linije z usmerjenim vrtanjem (ISO 21225-2:2018)

Ta mednarodni standard določa zahteve in preskusne metode za cevi in fitinge, ki so del plastičnih cevnih sistemov za zamenjavo različnih cevovodnih omrežij, ki so položeni v zemljo, podzemnih omrežij za odvodnjavanje in kanalizacijo, ki delujejo po težnostnem principu, ter podzemnih omrežij za oskrbo z vodo in s plinom brez izkopa na podlagi usmerjenega vrtanja ter udarnega kopanja.
Uporablja se za polietilenske (PE) cevi in fitinge, kot so izdelani, ter za nameščeni sistem zamenjave.
Ta standard naj bi se uporabljal v povezavi s standardi za izdelavo cevnih sistemov iz polietilenskih cevi, če so na voljo.
V zvezi z izdelanimi cevmi se uporablja za tri različne vrste polietilenskih cevi:
– PE trdne stenske cevi iz ene plasti (nazivni zunanji premer, dn) s kakršnimi koli identifikacijskimi črtami;
– PE cevi s koekstrudiranimi sloji na zunanji in/ali notranji strani cevi (celotni zunanji premer, dn), kot je opredeljeno v dodatku A, pri čemer imajo vsi sloji enako oceno MRS;
– PE prevlečene cevi (zunanji premer, dn) s termoplastičnim dodatnim slojem, ki ga je mogoče odluščiti, na zunanji strani cevi (»prevlečena cev«), glejte dodatek A.
Poleg tega zajema:
– spajanje dolžin cevi prek soležnega taljenja za oblikovanje neprekinjenega niza pred namestitvijo;
– izdelane in brizgano lite fitinge iz PE.
